IMPROVEMENT IN` POLISH-ROD ADJUSTERS FOR ARTESIAN AND OTHER WELLS.

Specification forming part of Letters Patent No. 222,336, dated December 2, 1879 application filed May 9, 1879.

To all whom it may 001100751:

Be it known that' I, OWEN B. WICKHAM, of

when adjusted without'bending or springing the rod, and from which the rodean be readily removed when desired.

In the drawings, Figure l is an end view of the adjuster as attached to the walking-beam, and with the polish-rod in place. Fig.v2 isa side `View ot the same; Fig. 3, a section-on line w y.

A is the walking-beam; B, the body'of the 1 adjuster, made'of iron or-any suitable metal.- u The upper part :isv made flat-,with a vertical triangular groove, F, along the center, into which the polish-rod G lies. V The rod is confined `in place by the hooks j 'D'D,the inside of the hooks being also triangular, corresponding with the groove in B.

When the polish-rod C is adjusted, the hooks are drawn close by the nuts `E E, and the rod is held firmly in place inthe groove F, and is not liable tok become crooked.

The groove and hook being triangular allows the use of rods of different sizes,all being held equally rrn.

, When it is desired to remove the rod, all that is required is to loosen the nuts` E E sufficiently to allow the hooks to be turned, as shown in the dotted lines in Figi..v

The lower portion of the plate B. is constructed of the link or slot G, and is madeto t into a journal in the top of the walkingbeam A. A piece of plank, H, is laid inside the slot G and bolted firm to the walkingbeam, thus securing the adjuster and `allowing free motion backward and forward, and when the polish-rod is removed the adjuster can be laid back on the Walking-beam. A slot is cut through the Walking-beam to allow thepassage of the rod.`

I claim as my invention A polish -rod adjuster constructed of thel plate B, with triangular groove F, hooks DD, withnuts E E, and with slot G, substantially as described, and for the purposes herein set forth.
